Application filed March 13, 1911.

Patented July 4, 1911. Serial No. 614,141.

To all whom it may concern:

Be it known that I, EDGAR JAMEs, a citizen of the United States, residing at Lincolnton, in the'county of Lincoln, State of North Carolina, have invented a new and useful Plow, of which the following is a specification.

This invention relates to that class of stirring or turning plows which are at the same time adapted for use as subsoilers, the several parts being operative either conjointly or singly and successively, as will hereinafter more fully appear. in connection with the complete description and the accompanying drawings, in which- Figure l is a side elevation of the plow with the subsoiler projected; Fig. 2 is a similar view, partly in section, with the subsoiler in its normal elevated position; Fig. 3 is a plan view; Fig. 4 is a cross section on the line 44 of Fig. 2; Fig. 5 is a detail of one of the beams; Figs. 6 and 7 are details of the lever devices, and Figs. 8 and 9 are details of the subsoiler hereinafter described.

Throughout the following description and the accompanying drawings similar parts are referred to by like reference characters.

his improved plow comprises a pair of twin beams 10 and 11, the former or pri mary beainbeing stationary and secured rigidly in any approved manner to the turning plow indicated somewhat conventionally as having a landside l2 and a moldboard 13. The secondary beam 11 is pivotally connected at 14 to the front end of the primary beam, and at its rear end is movable downwardly between the landside and the moldboard. This secondary beam carries at its base or heel a subsoil share or bit 15, and the form and disposition of the twin beam are such that practically the whole of their combined strength is availed of in all adaptations of the implement.

. As a simple and effective means to manipulate the secondary beam and subsoiler I have illustrated a hand lever 16, within convenient reach of the driver, permanently pivoted shoulder 18 of the subsoil beam. This lever in any pair of alining holes a a, .7) b, or c 0, according to the depth to which it may desired to throw the subsoiler below its normal inoperative or elevated position. normal elevation of the secondary beam being a constant, its downward throw will always be substantially equal to twice the distance between the pivots l7 and 21, and the pivot 21 should be inserted in said holes pairs so that the combined and link will be thermore, the pivot 21 swings with the lever around the p' 7 in an are slightly greater than 180 degrees so that as the pivot just passes, at each end of its movement, the line joining the pivots l7 and 20, the lever and link constitute a substantial lock for the subsoiler in any position of adjustment, such lock however being easily broken by hand operation of said lever when desired. Should occasion demand a more positive locking means for the hand lever, the same purpose a dog 23, 24, and adapted to engage the aforesaid eX- tension 18 in either position of adjustment in a well known manner.

The rear edge of the secondary beam 11, below the extension 18, is adapted to engage a lug 25, shown as carried by the primary heel engages a fixed stop or lug 26, carried on any convenient stationary member at the moldboard, as upon the beam 10, through which the combined strength of the gether, therefore, need scarcely be heavier for sharpening and comprises a shank l5, secured in the socket 11 at the heel of the beam 11, and a shoe 15 which extends pivot pm or bolt 21 adapted to be inserted rearwardly beneath and in contact with said during ordinary use of the moldboard, a

to the other to project the subsoiler bit below the moldboard, and means whereby the combined strength of both beams is made applicable to the subsoiler when projected, substantially as set forth.

2. The combination of a moldboard, a primary beam secured thereto and having stop lugs at its top and rear portions, a secondary beam pivoted to the front end of the primary beam, a subsoiler bit carried by the secondary beam, and hand operated means to throw and lock the secondary beam either up or down in engagement with the aforesaid lugs respectively, forth.

3. In a plow, the combination of a moldboard, a stationary beam secured thereto, lugs, one at the top of said beam and another at the moldboard, a subsoiler beam movably related to the aforesaid beam, means to lock the beams together with the top of the latter beam against the one lug and with the front part of its lower end against the other lug.

In testimony whereof I have hereunto afiixed my signature in the presence of two subscribing witnesses.

heel to protect the same and to prevent the bit from turning or twisting about the axis of the shank.

The implement may used as a side-hill plow, for after a furrow is made in the usual way by the turning plow, by a simple manipulation of the lever 16 the subsoiler may be thrown down and applied to the same furrow in the reverse direction, the means for changing from one form of the plow to the other being so easy of operation as to enable it to be accomplished while the team is making the turn at either end of the furrow and without a moments loss of time.

The several parts of the plow may be made of any materials that may be considered best adapted for their purposes, and I wish too to be understood as not intending to be limited to the specific details illustrated, reserving the right to vary therefrom without departing from the spirit of the protection hereby obtained.

I claim:
